GForce Arms GFP3REX 12 Gauge 20-inch Pump Shotgun
About this product
What is the GForce Arms GFP3REX 12 Gauge 20-inch Pump Shotgun? It's a 4+1 capacity pump-action shotgun built around a 20-inch stainless steel barrel with a black synthetic pistol grip and Cerakote finish, designed for practical applications like home defense and field use. This firearm accepts both 2" and 3" shotshells while maintaining an overall length of 29.75 inches and weighing approximately 6.8 pounds empty. Its straightforward operation and modern touches like accessory rails make it a utilitarian choice for shooters who prioritize reliability over refinement.
What is the GForce Arms GFP3REX used for?
This shotgun is built for close-quarters home defense and general-purpose field applications where reliability matters more than precision. The 20-inch barrel provides manageable maneuverability in tight spaces while still offering effective patterning with buckshot or slug loads within 25 yards. I'd recommend it for vehicle or cabin defense scenarios where its 4+1 capacity and simple manual of arms reduce operator error under stress.
How does the GForce Arms GFP3REX compare to the Stevens 555 Sporting O/U?
The GFP3REX is better for defensive use while the Stevens 555 Sporting excels at clay targets. The Stevens 555 Sporting O/U 12 Gauge 30in offers superior balance and dual triggers for competitive shooting but costs over $600 more and lacks accessory rails. For $186.99, the GFP3REX delivers brutal functionality where the Stevens prioritizes refinement—choose the pump gun for duty use and the over-under for recreation.
What does it weigh and what are the dimensions?
Unloaded weight is 6.8 pounds with an overall length of 29.75 inches and barrel length of 20 inches. The pistol grip contributes to a compact profile that's 5 inches shorter than most full-stock shotguns, making it suitable for storage in vehicles or tight spaces. The 12-gauge bore diameter is standard .729 inches, and the magazine tube holds four 2¾" shells with one in the chamber.
Who is this NOT for?
This isn't for competitive shooters or those wanting a soft-shooting range toy. The pistol grip configuration transfers more recoil to the wrist than a traditional stock, and the 4+1 capacity limits sustained fire compared to extended tube shotguns. If you need high-volume shooting or refined ergonomics for clay games, consider the Stevens 555 Sporting O/U instead.
What's in the box?
You get the shotgun, one removable magazine plug, and basic owner's documentation—no case, cleaning kit, or additional chokes. The plug allows capacity configuration for hunting regulations, but you'll need to supply your own lubrication and tools for maintenance. Expect to spend another $30-50 on a basic cleaning rod, patches, and solvent for proper upkeep.
Is the GForce Arms GFP3REX worth it at $186.99?
At under $200, it's a functional tool that outperforms its price point for sheer reliability. You're getting a stainless steel barrel, Cerakote corrosion resistance, and Picatinny rail compatibility that usually starts around $300 in other brands. Just don't expect smooth aesthetics or refined ergonomics—this is a working firearm, not a showpiece. For budget-conscious buyers needing a no-frills defender, it's objectively worth the money.

Frequently asked questions
- Is it compatible with choke tubes?
- No, the GFP3REX features a fixed cylinder bore with no choke threading. The 20-inch barrel is designed for open patterning with buckshot or slugs, not adjustable constriction. If you need choke compatibility, consider the Stevens 555 series with interchangeable chokes.
- Does it fit standard shotgun slings?
- Yes, it accepts standard 1-inch sling swivels via the integrated front and rear mounting points. The rear swivel mounts to the pistol grip base, while the front uses a barrel band design. You'll need to purchase swivels separately—expect to spend $15-25 for a quality set from Uncle Mike's or similar.
- How long does shipping take?
- Firearms ship within 3-5 business days to your selected FFL dealer after verification. Transit time varies by carrier but typically adds 2-7 days depending on location. All shipments require adult signature and FFL coordination—factor in an extra 24-48 hours for dealer processing upon arrival.
- Can I return it if it doesn't fit?
- Firearms are generally non-returnable due to federal regulations, but Ironclad Armory allows exchanges within 14 days for manufacturing defects. You must initiate the process within 48 hours of FFL pickup and provide video evidence of the issue. All returns require coordination with the original FFL and incur a $45 restocking fee.
- Does this work with Magpul accessories?
- The Picatinny rail section accepts Magpul MOE accessories like lights or lasers, but the pistol grip isn't compatible with aftermarket replacements. The grip is molded as part of the receiver assembly, so you're limited to rail-mounted additions only. For full customization, consider a shotgun with modular grip systems.
